Definitions
- the present invention in some embodiments thereof, relates to cancer diagnosis and, more particularly, but not exclusively, to methods and systems of evaluating a risk of cancer.
- a diagnosis of colorectal cancer includes diagnosis based on the immunological fecal occult blood reaction, diagnosis by colonoscopy, and the like.
- diagnosis based on a fecal occult blood test does not serve as definitive diagnosis, and most of the persons with positive-finding are false-positive.
- both the detection sensitivity and the detection specificity become lower in the diagnosis based on a fecal occult blood test or the diagnosis by colonoscopy.
- early cancer in the right side colon is frequently overlooked when diagnosed by a fecal occult blood test. Diagnostic imaging by CT (computer tomography), MRI (magnetic resonance imaging), PET (positron emission computerized-tomography) or the like is not suitable for the diagnosis of colorectal cancer.
- colorectal biopsy by colonoscopy serves as definitive diagnosis, but is a highly invasive examination, and implementing colonoscopic examination at the screening stage is not practical. Furthermore, invasive diagnosis such as colonoscopy gives a burden to individuals such as accompanying pain, and there may also be a risk of bleeding upon examination, or the like.
- U.S. Patent Publication No. US 2010/0009401 describes a method of evaluating colorectal cancer, where amino acid concentration data on the concentration value of amino acid in blood collected from a subject to be evaluated is measured, and a colorectal cancer state in the subject is evaluated based on the concentration value of at least one of Arg, Cys, Om, Trp, Glu, ABA, Val, Phe, Leu, GIn, Ile and His contained in the measured amino acid concentration data of the subject.
- US Patent No. 6,059,724 teaches a computer-based system for predicting future health of individuals comprising: (a) a computer comprising a processor containing a database of longitudinally-acquired biomarker values from individual members of a test population, subpopulation D of aid members being identified as having acquired a specified biological condition within a specified time period or age interval and a subpopulation D being identified as not having acquired the specified biological condition within the specified time period or age interval; and (b) a computer program that includes steps for: (1) selecting from said biomarkers a subset of biomarkers for discriminating between members belonging to the subpopulations D and D, wherein the subset of biomarkers is selected based on distributions of the biomarker values of the individual members of the test population; and (2) using the distributions of the selected biomarkers to develop a statistical procedure that is capable of being used for: (i) classifying members of the test population as belonging within a subpopulation PD having a prescribed high probability of acquiring the specified biological condition within the specified
- US Patent Application No. 2006/173717 teaches that personal and family health history information can be used to assess familial risk of disease. For example, information can be collected about the disease history of a person and the person's first-and second-degree relatives and then analyzed to determine the familial risk of common diseases such as coronary heart disease, stroke, type 2 diabetes, and colorectal, breast, and ovarian cancer. Assessed familial risk of disease can then be used by researchers to better estimate the contribution of personal history and family history to the etiology and natural history of a disease of interest, and by consumers and health professionals to determine recommendations for disease management, prevention and screening that are personalized and targeted to the familial risk.
- common diseases such as coronary heart disease, stroke, type 2 diabetes, and colorectal, breast, and ovarian cancer.
- Assessed familial risk of disease can then be used by researchers to better estimate the contribution of personal history and family history to the etiology and natural history of a disease of interest, and by consumers and health professionals to determine recommendations for disease management, prevention
- KOULAOUZIDIS ANASTASIOS ET AL "Hemoglobin and red cell indices as predictors of gastrointestinal malignancy", AMERICAN JOURNAL OF GASTROENTEROLOGY, ELSEVIER SCIENCE INC, US vol. 101, no. 9 Supplement S2, 1 September 2006 (2006-09-01), page S134, XP008177675 , teaches that Hemoglobin and red cell indices may be predictors of gastrointestinal malignancy.
- LALITHA MAHADAVAN ET AL "Exfoliated colonocyte DNA levels and clinical features in the diagnosis of colorectal cancer: a cohort study in patients referred for investigation", COLORECTAL DISEASE, vol. 14, no. 3, 7 February 2012 (2012-02-07), pages 306-313 teaches that in a selection of patients for investigation of suspected colorectal cancer DNA isolated from exfoliated cells collected from the rectum may be measured. The article concludes that quantification of exfoliated DNA from rectal cellular material has promise in the diagnosis of colorectal cancer, but this requires confirmation in a larger study.

- the performance of each one of the classifiers is estimated using a 10-fold cross validation process where the evaluation dataset, referred to herein as a population, is randomly split to ten equal-sized parts. For each part, the following may be performed:
- classifications are collected to measure performance of each classifier.
